A drive system includes an engine as a drive source, a lead storage battery that is charged using the engine as a motive power source, a starter that starts up the engine by being driven by electric power from the lead storage battery, and a voltage sensor that measures an inter-vehicle voltage of the lead storage battery. A control device that is applied to the drive system determines that the battery has been degraded, when a voltage difference between a first battery start-up voltage and a second battery start-up voltage is larger than a preset degradation determination threshold, the first battery start-up voltage being measured by the voltage sensor when the starter is driven, the second battery start-up voltage being measured by the voltage sensor when the starter is driven at a different timing from a timing when the first battery start-up voltage is measured.
